67' 318 crank in a 69' 340

If anyone knows a good cast crank welder in the So.Cal area that will work for beer, I got a old school stroker (360 to 340 mains) that has a chipped flange. Fed Ex dropped it on its end. I still got the piece. I had a 318-3 crank once. Also had a forged 318 poly crank that P.A.W. 'remanufactured' to 340 specs. Worked great.
